[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model.

[0021] See Figure 1-4 A dry laminating machine unwinding mechanism includes an unwinding roller 1 and a pair of bearing seats 2. The surface of the unwinding roller 1 has multiple axially arranged grooves 3 in a circular array. Sliding counterweights 4 are embedded within the grooves 3, with the upper surface of the counterweights 4 lower than the height of the grooves. Bearings 5 ​​are installed inside the bearing seats 2. The left and right shaft ends of the unwinding roller 1 are embedded in the bearings 5. Elastic rubber damping rings 6 are installed outside the bearings 5. Either the left or right shaft end of the unwinding roller 1 is connected to a drive motor 8 via a bellows coupling 7. Specifically, during use, the counterweights 4 rotate with the unwinding roller 1. When dynamic imbalance occurs, an eccentric force is generated, causing the counterweights 4 to slide under the influence of the eccentric force, correcting the dynamic balance in real time and adapting to different roll material specifications. The elastic rubber damping rings 6 absorb radial vibration and suppress vibration. The drive motor 8 and the unwinding roller 1 are connected by a flexible coupling 7, which reduces transmission impact and improves operational stability.

[0022] In this embodiment, the slide 3 has a T-shaped structure, the counterweight 4 is fitted with the slide 3 with a clearance, and plugs 9 are provided on the left and right sides of the slide 3. The plugs 9 are fixed with bolts 10. The counterweight 4 is inserted and installed from either the left or right end of the slide 3, and then the plugs 9 are used to seal the two sides of the slide 3 to prevent the counterweight 4 from falling out of the slide 3.

[0023] In this embodiment, the plug 9 is made of rubber, which can buffer when it is impacted by the configuration block 4, thus avoiding excessive noise.

[0024] In this embodiment, a Teflon coating 11 is provided on the surface of the groove 3 to reduce frictional resistance and extend service life.

[0025] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
